Medical necessity documentation that matches clinical reality and payer expectations.

Medical necessity denials are often triggered by documentation that is incomplete, vague, or misaligned with payer definitions — even when testing is clinically appropriate.

Cellarian bridges that gap.

How Cellarian generates medical necessity documentation

Cellarian:

  • Automatically interfaces with LIMS, EHR or middle-ware platforms

  • Pulls structured and unstructured clinical data

  • Applies payer-specific medical necessity criteria

  • Generates patient-specific justification text

  • Creates a clear, defensible documentation trail

Documentation is designed to withstand audit review.

Toxicology documentation often fails due to:

  • Overly generic, “copy and paste,” and templated language

  • Missing or incorrect treatment context

  • Inconsistent justification across encounters

Cellarian generates patient-specific documentation that:

  • Delivers a unique provider summary detailing the patient’s individualized diagnoses, medications, risk levels, days of abstinence (if appropriate), and ongoing treatment and monitoring needs.

  • Aligns with payer frequency and necessity standards

  • Supports both presumptive and definitive testing

Medical necessity for Molecular PCR testing

For molecular diagnostics, payers expect clear linkage between:

  • Provider listed Symptom

  • ICD-10 specific

  • Code set and bundled code specific

  • For labs with or without T.A. Authorizations

  • For MolDX and non-MolDx states

  • Clinical Risk factors

  • Test or Bundled testing selections

Cellarian supports medical necessity documentation for:

  • Respiratory pathogen testing

  • UTI and recurrent infection testing

  • STI testing

  • Women’s health panels

  • Wound testing

Each order is supported by patient-specific clinical rationale.

Strengthen documentation before it becomes a denial.
